ABSTRACT:
A braze material is provided for repairing an article, and particularly components formed from cobalt and nickel-base superalloys, such as gas turbine engine components. The braze material is composed of high melt particles distributed within a braze alloy. The braze alloy can be any suitable bonding material of the type used to repair components that must operate at high temperatures. The particles are single crystal, directionally solidified or equiaxed particles formed from a superalloy or ceramic material, or mixtures thereof. Importantly, the particles have an aspect ratio (length to width) of at least 4:1. The braze material can be provided and used in the form of a slurry, a presintered preform, a plasticized tape, or in a powdered form.
